The mitochondrial genome analysis of Flavoperla hatakeyamae (Plecoptera: Perlidae).

ABSTRACT: In this study, we analyzed the entire mitochondrial genome of Flavoperla hatakeyamae, which has 15,730 bp in length. This complete mitochondrial genome possessed 13 protein coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 control region. The nucleotide composition of the complete sequence of mitochondrial genome was accounting for 35.0%, T for 31.3%, C for 21.2%, G for 12.5%, and A + T for 66.3%. Among the 13 protein-coding genes, the starting codon of 12 protein-coding genes was ATN except the starting codon of COII was ACC. In addition, 11 of the protein-coding genes used conservative termination codon TAA/TAG, except for COII and ND5 which terminated by a single T. Based on Bayesian (BI) and maximum-likelihood (ML) methods, we found that the genus Flavoperla and Niponiella were gathered into one branch and the species of Perlinae were clustered in one clade.

Project description:Of the roughly 400 species of Perlidae in the world, most species are widely distributed in the northern hemisphere, but a few can be found in South Africa and South America. There are only five species in the genus Flavoperla of the family Perlidae in China. To gain a better understanding of the architecture and evolution of mitochondrial genome in Flavoperla, the entire mitochondrial genome (mitogenome) of a Chinese Flavoperla biocellata Chu, 1929 from family Perlidae (Insecta: Plecoptera) was sequenced. The 15,805-bp long mitochondrial genome of F. biocellata contained 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and a putative control region (CR). The gene arrangement of F. biocellata was identical with that of other stoneflies and with the fly Drosophila yakuba. Most PCGs of F. biocellata used the standard ATN start codons and complete TAN termination codons. Twenty-one of the 22 tRNA genes exhibited cloverleaf secondary structures, but the dihydrouridine (DHU) arm of trnSer (AGN) was completely reduced. Phylogenetic analyses with both Bayesian inference (BI) and maximum likelihood methods (ML) generated similar topology, both supporting the monophyly of all stonefly families and the infraorder Systellognatha. The phylogenetic analysis based on mitochondrial genomic data from 30 stonefly species recovered a well-supported tree resolving higher-level relationships within Plecoptera. The northern hemisphere suborder Arctoperlaria divided into two groups, Euholognatha and Systellognatha. The southern hemisphere suborder Antarctoperlaria formed two clades: Eustheniidae+Diamphipnoidae and Austroperlidae+ Gripopterygidae; consistent with relationships proposed based on morphology. The final relationships within Plecoptera were recovered as (((Perlidae+(Perlodidae+Chloroperlidae))+(Pteronarcyidae+(Peltoperlidae+Styloperlidae))) +(Taeniopterygidae+(Capniidae+(Nemouridae+Notonemouridae))))+ (Gripopterygoidae+Eusthenioidae).
